Some revolutions are not begun with a bang or a shout. Some revolutions quietly appeal to the senses, the intellect and even the soul. They are born out of constant thought and intense passion to effect change and to drive progress. At Kaenon Polarized, we strive to evolve our world optically. This pursuit has led Kaenon Polarized to create the world s first Luxury Performance eyewear brand - utilizing the most advanced polarized lens technology on the planet. Glass wasn t strong enough. Polycarbonate wasn t clear enough. So we set out to develop our own, completely new polarized lens material. Something with the superior optical quality of the finest glass, yet the lightweight impact resistance of polycarbonate. The SR-91 lens was created, and overnight, the optical world was forever changed. No other polarized lens blocks the blinding rays of glare with the unbeatable clarity and impact resistance of the SR-91 lens. Kaenon Polarized merges high fashion with sports function in the Luxury Performance collection. With outstanding polarized optics and lightweight injection-molded frames, Kaenon offers a variety of distinctive styles for the beach volleyball court or the boardwalk patio. We are sure you ll find the perfect fit with styles like Georgia, Bolsa, Jetty and Rhino here at Zappos!.
